Aim of study: Hearing loss caused by exposure to recreational noise is considered a devastating disability, not least because it is virtually 100 percent preventable. No consensus exists regarding the magnitude of the risk. This study prospectively assesses the hearing threshold in a group of Portuguese adolescents, related to their habits of noise exposure. Method: […]
The appearance of tinnitus has risen clearly also in children within the last decades. 1550 children were questioned as to whether they have tinnitus. A total of 131 children said at the interview that tinnitus had appeared or was still present. The most frequent information was the progression of an existing hardness of hearing followed […]
Masking of tinnitus is possible using high audio frequencies and low-frequency ultrasound. The mechanisms involved in reception and perception of both audio frequencies and ultrasound are identical, with the exception that ultrasound interacts with an intermediary site, the brain. We proposed brain ultrasonic demodulation as the means of place-mapping ultrasound on the first few millimeters […]
It has long been suspected that an important relationship exists between inner and outer hair cells, and that a disturbance of this relationship could lead to the phenomenon of tinnitus. The electromodel of the auditory system describes one mechanism of this inter-hair cell relationship. Following this model a mechanism exists, driven by mechanosensitive outer hair […]
Psychological aspects are often underlined in generation of tinnitus so we assessed the neuropsychological status in our group of patients. We also found increased number of abnormal ENG recordings in tinnitus patients so the aim of this study was to compare the ENG outcome with their neuropsychological status. The study was carried on 69 subjects […]
Introdução: O diagnóstico precoce de surdez infantil é um requisito essencial para uma correcção apropriada da hipoacusia. Até recentemente o rastreio auditivo baseava-se exclusivamente na avaliação dos Potenciais Evocados Auditivos do Tronco Cerebral (PEA), um método exigente em termos técnicos, demorado e que implica frequentemente uma sedação da criança. O advento das Otoemissões Acústicas (OEA), […]
Eighty patients with sudden hearing loss and seventy patients with a chronical cochlear function decreasing have been treated until now with intravenous infusion of a recombinant glycoprotein analogous tissutal plasminogen activator (rt-PA): 3mg dissolved in 250mg of physiological saline given every 12 hr intravenously. Specifically excluded were patients with abnormal known coagulation. No patient was […]
Hyperacusis is mainly a consequence of the noise level in the twenty-first century, owing to dramatic changes in people’s lifestyles. Of every 100 people with otological complaints (e.g., tinnitus and hyperacusis), 20 are affected by hyperacusis. Because of its high incidence, this symptom has long been the subject of investigation.Nine patients (eight female, one male) […]
Introduction: Acupuncture is a therapeutic technique based on the concepts of the Traditional Chinese Medicine, which mechanism of action could be explained by the efferent nervous system from stimulation of specific points on the body surface. Aim: The objective is to study the acupuncture effects in the treatment of tinnitus, and the changes provoked on […]
During the last years, cellular phones produced a real, total and incontrovertible revolution, involving the whole social and environmental domain. However, to date, there is only a reduced knowledge on what are the biological systems influenced by the use of this kind of devices. Among them, the produced electromagnetic fields (EMF) could affect, before any […]
